Surface area of a sphere = 4 x (pi) x (radius)2
4(pi)r^2 (4 * pi * r^2)
How do you find the suface area of a net? Answer: Do the formula for each shape that is in the net.
Surface area = 4*Pi*radius2
To do this question, we have to ask ourself, what formula do you use to find the surface area of a sphere. The answer should be known to you, but it is 4πr2. Since we know how to find the surface area for a full sphere, then finding the surface for a half sphere is just half the job. You use the formula for the full sphere 4πr2, and divide it by 2... so (4πr2) / 2 . Voila!
Assuming the moon to be a sphere, the formula to find its surface area is 4/3*pi*r^3 where r is the radius of the moon.
4(pi)r^2 (4 * pi * r^2)
How do you find the suface area of a net? Answer: Do the formula for each shape that is in the net.
Use the formula for volume to solve for the radius of the sphere and then plug that radius into the formula for the surface area of a sphere.
Just add the area of the six squares - that gives you 6a2, where a is the length of one side.
Surface area = 4*Pi*radius2

Use this formula: 4 x pi x radius2
To find the surface area of a sphere, the formula is: 4pi*r2So plug in numbers: 4pi(4)24pi(16)=64pi
(pi)R2 is the formula for the area of a circle. It won't help you find the volumeof a half sphere, at least not without some calculus.What you need is the formula for the volume of a sphere: V = 4/3 pi R3 .Do I have to explain that the volume of a half sphere is just half of that ?
Use this formula (Ï€ = Pi): Surface area = 4Ï€r2
The surface area of a sphere is 4 π r2. Since a hemisphere is half of a sphere, the equation will be 2 π r2.
